That doesn't make u a bad daughter. it makes u a bad daughter for ur mother. We all have dreams in our heads and she probably had a dream of what her daughter would be like, and you weren't it, that's it.
I'm 17 and i don't feel like a bad daughter and i hate my mother. She played the favoritism card. I have an older brother and everything is about him, even though he's an "adult." I wanted a mother who would talk to me about how to be a woman, or even give me a book about how to be a woman, anything but she gave me nothing, but misery. We can't just be in the middle with our love or like for each other, it's either i'm doing her bidding, being a slave or needing my teenage space and she ignores me.
I hate her b/c she was never there for me. she let things happen to me and did nothing. When I hear stories about a mom letting her daughter be molested or raped by a step-dad or boyfriend and not believing their daughter, I get so angry, so disgusted cause sometimes in the end the daugther says I still love my mom. That makes me want to barf, i could never love my mother after that.
